Which schools are suitable for installing cell phone signal jammers
The mobile phone signal jammer uses the same frequency as the downlink frequency of the mobile phone receiving base station to conduct electromagnetic interference of the same frequency.
In school exams, in order to prevent students from using mobile phones to transmit information, leak test papers, and cheat in exams, some are also to prevent teachers from leaking test paper information on the way to escort the test papers, which will have a bad impact on the later exams.

The cell phone signal jammer is relatively small and can be fixed on the ceiling or wall with ordinary screws. Of course, it can also be used directly on a table or something. However, in this case, the effect is not very good. After installation, check to see if everything is connected well, and if there is any problem with accessories such as power supply.
GPS jamming should be placed in a well-ventilated place, try to avoid open objects, and avoid strong electromagnetic sources of strong heat sources to ensure the shielding effect and long-term GPS jamming work. Do not stack other items on it and remove the antenna. , so as not to affect the shielding effect and damage the machine.
Since the power supply and antenna are dedicated to the host, and they are debugged one by one during factory debugging, please try not to use them interchangeably to ensure the best effect. When the area of the site used is larger than the effective shielding range, it is recommended to use multiple isolators for cellular installation to ensure the shielding effect.
Please keep away from corrosive gases and liquids, and do a good job of dustproof and moisture-proof, so as not to accelerate the aging of the internal components of the equipment.
